ABSTRACT:
A labeling device (20) is provided which is especially designed for use as a transverse labeler with in-line packaging machines (22). The device (20) includes a label dispensing unit (34), and a transport and tamping assembly (36) with a tamping assembly (68). The assembly (68) has a plurality of side-by-side hollow upright plates (78) presenting label-engaging ends (80) and remote ends (82), with the plates (78) secured with movement in unison to a slotted crosspiece (84); an air cylinder assembly (98) is coupled with the crosspiece (84) for selective movement of the plates (78). Apparatus (100) is also provided for creating reduced pressure conditions at the ends (80) of the plates (78), including fans (104) oriented to draw air through the hollow plates (78). The transport and tamping assembly (36) is adjustably mounted to the labeler frame (38) in order to permit selective adjustment of the assembly (36). Specialized rollers (134) having perforate roller bodies (136) and supporting bearings (140) are used in the web-handling portion of the preferred device (20).
